Patent ES-8307488-A1 (ES)
Title: Exerciser for strengthening muscles of legs
IPC: A61H1/02
Filed: 1982-03-12
Abstract: The exercising device includes right and left leg supports (22) which are mounted for rotation relative to a torso support (18) about an axis coinciding with the user's hip joint. A linking mechanism connects the two leg supports to restrict their movement to equiangular bilateral rotation towards and away from each other. This ensures that the legs are exercised in a balanced way. - A weight stack (40) is connected by a chain (41) to a sprocket mounted on a back shaft. The shaft also has a pair of freely rotatable sprockets which transmit a variable force via a pair of chains to the leg support mountings. The amount imposed on each leg support can be varied by the user to resist movement of the supports towards or away from each other.  (1/11) EPAB- EP--60063 B Apparatus for exercising abductor or abductor muscles of the legs of a user, and comprising: torso supporting means (16,18) for supporting the user's upper body, leg support means (20) comprising right and left leg supports (22) for respectively supporting and engaging the user's right and left legs,  means (28,29) mounting each of said leg supports (22) for rotation relative to said torso supporting means about an axis extending through the corresponding hip joint of the user, and resistance means (40,41) operatively connected to said mounting means for imposing on said leg support means (20) a force resisting movements of said leg supports (22) in at least one of directions away from and toward one another, said resistance means comprising variation means (57,58) for charging the amount of force imposed in predetermined relationship to movement of said leg supports (22) away from and toward one another, characterised in that said mounting means (28,29) comprises a linking mechanism  operatively connecting said right and left leg supports (22) for restricting movement thereof to equiangular bilateral rotation away from and toward one another and thereby facilitating balanced exercise of right and left legs.

(12pp) USAB- US4478411 A A torso support is provided for supporting a user's upper body and a leg support for the user's leg. The leg support and torso support are connected together to accommodate rotation of the leg support relative to the torso support and about an axis extending through the corresponding hip joint of the user. - A resistance is provided for imposing on the leg a support force resisting movement of the leg support in at least one of directions of away from and toward the user's other leg.
